1. MTest Pixel Telescope – Status Update David Christian January 8, 2008

2. Detector Status/Plan Hybrid development complete –11 good hybrids in hand –Balance in process at VTT Delivery Jan – Feb (less schedule risk than before) Module development –4x HDI prototype received & tested (12 good parts in hand). –Production purchase requisition is working its way through the FNAL bureaucracy (Feb delivery expected).

3. Detector Status/Plan continued Plane/Station development: –First prototype plane being tested (one of three pixel modules mounted so far). –SLINK pcb prototype has been received, stuffed, & testing has begun (Nevis). Box/Area: –Mechanical design to be coordinated with needs of LHCb VELO (1st users) - waiting for MOU to be signed (momentarily).

4. Plane prototype on CMM

5. 1 st module ready to test

6. DAQ Status/Plan DAQ Hardware/Firmware (Nevis) –PCI interface ~90% complete (trigger/timing hooks not written) –Router ~70% complete (trigger/timing, implementation of merges, integration of DUT?) –SLINK Design complete. Prototype fabricated; tests begun. On the optimistic critical path - hoping to begin testing with a prototype station (or at least a plane) ~ Feb 1.

7. Software Status/Plan Online software (FNAL, Syracuse, UNM?) –Core low level routines exist & have been tested. –Need to specify online, including online/offline boundary, write & test code. On the optimistic critical path Offline software (Syracuse, FNAL?, UNM?) –Data unpacking –Alignment –Tracking, integration of DUT On the optimistic critical path This task has lagged. Strategic decisions to be made in the next 2-4 weeks.

8. Schedule Focus on full telescope ASAP. February doesn’t look possible. March?

9. MTest Telescope Constructed using “BTeV pixels” Pixel size = 50  x 400  (600  ) Oriented to provide “precision-x” or “precision-y” measurements.

10. Layout Aperture ~ 3.5cm x 3.5cm 4 – 6 stations Beam x y x y

11. Nomenclature Station = 2 planes & an SLINK Plane = 3 modules mounted on a TPG heat spreader Module = hybrid pixel detector glued & wire-bonded to a High Density Interconnect (Kapton flex circuit) Hybrid = pixel sensor bump bonded to 4 FPIX2.1 ASICs

12. DAQ Overview SLINK ROUTER Twin-ax (sATA) PCI Interface Fiber Trigger/timing signals LINUX pc Removable disk

13. DAQ SLINK communicates with 2x3x4=24 FPIX2.1 chips & with ROUTER. –Relays commands & responses –Collects data Deserialize (digital phase follower) Time order & construct data blocks w/extended time stamp & chip ID headers Hierarchy of 2-way data merges

14. DAQ - continued ROUTER communicates with PCI interface & SLINKs and (optionally) DUTs –12 sATA ports, 4 RJ45 ports –Relays commands & responses –Collects data Hierarchy of 2-way data merges (same logic as SLINK) PCI Interface communicates with ROUTER & pc –Relays commands & responses –Uses 3 CSRs & 3 ring buffers in the pc main memory (64 MB)
